May 14, 2020 - ABB's synchronous reluctance (SynRM) motors offer a choice to meet the demand for energy efficiency. These motors now meet the IE5 ultra-premium energy efficiency class defined by the International Electrotechnical Commission (IEC). The IE5 level of efficiency is made possible by the SynRM design, which combines the performance advantages of permanent magnet technology with the simplicity and service-friendliness of an induction platform. To ensure an environmentally friendly design, the permanent magnets do not feature rare earth materials. Additional benefits of the IE5 SynRM motor are lower bearing and winding temperatures.
ABB IE5 SynRM motors can be used in a range of industrial applications where they offer accurate control and high efficiency across the whole speed range, even at partial loads. This makes them an upgrade option for standard induction motors in pumps, fans, and compressors as well as in more demanding applications like extruders, concha mixers, winches, and conveyors. IE5 SynRM motors are an replacement for induction motors as they have the same size and output power, so no mechanical modifications are required. The IE5 SynRM motors meet the requirements of the efficiency class defined in IEC TS 60034-30-2 and are available with output power of 5.5 to 315 kilowatt (kW) in frame sizes IEC 132-315.
They can be specified as part of a motor and drive package with ABB variable speed drives (VSDs).
